Eclipse CDT complains about unresolved functions but still builds successfully

The following C++ application compiles and runs successfully within Eclipse CDT but the IDE is still reporting an error stating:

Could not resolve function wprintf

#include <stdio.h>
#include <wchar.h>

int main()
{
  wprintf(L"Hello world");
  return 0;
}

The directory /usr/include (where wchar.h resides) is definitely listed within the Include path as otherwise the application would not compile. Hitting F3 on wprintf reports:

Could not find symbol 'wprintf' in index

This is my set up:

Does anyone know how I can get Eclipse CDT to resolve this function correctly?

At preferences -> c/c++ -> Editor -> Indexer disable indexer, apply, go back to preferences, and enable index again. This makes Eclipse to re-index the workspace. After that, my false red signs on the right side of the editor were gone.

I had the same problem with my Juno Release, Build id: 20120510-1218 on Fedora 14. To solve the index problem: Navigate to preferences -> c/c++ -> Editor -> Indexer -> uncheck "Allow heuristic resolution of includes"

-All the best

Ok, if /usr/include is listed correctly, then go to preferences -> c/c++ -> Editor -> Indexer -> select Indexer

Sometimes change it from fast c/c++ indexer to the Full one resolves the problem.

Hope it helps

I guess this directory is listed only in compiler Include path. This directory has to be listed in Eclipse C++ parser Include path as well, to resolve functions correctly.
